The invention discloses a turning road section identification method, system and device based on a GPS track, and a medium. The method comprises the following steps: obtaining a GPS track sequence; the GPS track sequence comprises a plurality of track points of one line and path vectors of two adjacent track points; presetting a radius, taking a track point in the GPS track sequence as a circle center, and making a first circular fence of the track point according to the radius; determining a pair of path vectors intersected with the circular fence corresponding to each track point, and calculating a path included angle of each pair of path vectors; taking the track points corresponding to each pair of path vectors of which the path included angles are greater than a first threshold as candidate track points to obtain a candidate track point set; and determining the turning road section according to the candidate track point set, so that the turning road section can be efficiently and accurately identified based on the GPS track sequence according to the radius and angle threshold value for identifying the turning road section.

    本申请公开了一种基于GPS轨迹的拐弯路段识别方法、系统、设备及介质,本方法通过获取GPS轨迹序列;所述GPS轨迹序列中包括一条线路的多个轨迹点,以及相邻两个轨迹点的路径向量;预设半径,以所述GPS轨迹序列中的轨迹点作为圆心,根据所述半径作轨迹点的第一圆形围栏;确定与每一个所述轨迹点对应的圆形围栏相交的一对路径向量,并计算每一对路径向量的路径夹角;将所述路径夹角大于第一阈值的每一对路径向量对应的轨迹点作为候选轨迹点,得到候选轨迹点集合;根据候选轨迹点集合确定拐弯路段,能够基于GPS轨迹序列,根据用于识别拐弯路段的半径和角度阈值,高效并准确识别出拐弯路段。
